A few nanoscale adjustments may be all that is required to make graphene-nanotube junctions excel at transferring heat, according to Rice University scientists. The Rice lab of theoretical physicist Boris Yakobson found that putting a cone-like "chimney" between the graphene and nanotube all but eliminates a barrier that blocks heat from escaping.
The research appears in the American Chemical Society's Journal of Physical Chemistry C.
Heat is transferred through phonons, quasiparticle waves ... read more

Vanilla aircraft proves to be anything but plain
A DARPA-backed small business effort broke boundaries for long-endurance flight this month by launching a uniquely designed, combustion-powered unmanned aircraft that stayed aloft for more than two days and two nights. The flight was terminated several days ahead of schedule because of incoming weather.
But the craft-built by Vanilla Aircraft of Falls Church, Virginia-landed safely with mo ... more

China Space Plan to Develop "Strength and Size"
China wants to develop "strength and size" in its space program, a China National Space Administration official said last week. In the next five years, the country plans to speed up the development of its space program. China wants to become the first country to carry out a controlled landing of a probe on the far side of the moon in 2018. China also has plans to launch its first probe to the pl ... more

AF looks to ensure cyber resiliency in weapons systems through new office
The Air Force, through its Life Cycle Management Center, has stood up the Cyber Resiliency Office for Weapons Systems (CROWS).
Although the office's primary operating location and senior leadership will be at Hanscom Air Force Base, contributing staff will come from various Air Force organizations and geographic locations. It will focus on integrating activities across the Air Force to ens ... more

Solar storms could spark soils at moon's poles
Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according to NASA-funded research. This alteration may become evident when analyzing future samples from these regions that could hold the key to understanding the history of the m ... more

ELFI: Engine for Likelihood-Free Inference facilitates more effective simulation
The Engine for Likelihood-Free Inference is open to everyone, and it can help significantly reduce the number of simulator runs.
Researchers have succeeded in building an engine for likelihood-free inference, which can be used to model reality as accurately as possible in a simulator. The engine may revolutionise the many fields in which computational simulation is utilised.
This dev ... more

U.S. Army selects Textron for Shadow UAV sustainment
Textron has received a $206 million contract to perform sustainment services for the U.S. Army's Shadow tactical unmanned aircraft system.
Support services covered in the contract include engineering, logistics, field service operations, depot materiel repair and post-productions software support. Textron officials say the agreement bolsters its ties with the Army and its fleet of 117 S ... more

Germanium's semiconducting and optical properties probed under pressure
Germanium may not be a household name like silicon, its group-mate on the periodic table, but it has great potential for use in next-generation electronics and energy technology.
Of particular interest are forms of germanium that can be synthesized in the lab under extreme pressure conditions. However, one of the most-promising forms of germanium for practical applications, called ST12, ha ... more

Lockheed Martin to build NASA's trojan asteroid explorer Lucy
Lockheed Martin has been selected to design, build and operate the spacecraft for NASA's Lucy mission. One of NASA's two new Discovery Program missions, Lucy will perform the first reconnaissance of the Jupiter Trojan asteroids orbiting the sun in tandem with the gas giant. The Lucy spacecraft will launch in 2021 to study six of these exciting worlds.
The mission is led by Principal Invest ... more

China to punish two top anti-corruption officials: Xinhua China's top anti-graft authority has punished two of its own senior officials for corruption and adopted new rules to supervise its investigators more strictly, state media said Monday.
The new regulations, passed at the annual meeting of the ruling Communist Party's Central Commission for Discipline Inspection (CCDI) over the weekend, seek to clarify how the country's 500,000 or so corrupti ... more

LIGO expected to detect more binary black hole mergers
The Laser Interferometer Gravitational-wave Observatory (LIGO) broke the news almost one year ago when the first-ever direct observation of gravitational waves was announced. Now LIGO scientists hope that this year could yield even more breakthrough findings in astronomy.
On November 30, LIGO resumed its search for gravitational waves when it was switched from engineering test runs to scie ... more

MIT researchers reveal new technique for measuring gravity
Researchers have found a way to improve atom interferometers, the most common and precise tool for measuring gravity.
Atom interferometers measure difference in wave characteristics between atomic matter. They rely on an exotic state of matter called Bose-Einstein condensates. Researchers in MIT have found a way to improve the precision of atom interferometers by augmenting the condensa ... more

The beating heart of solar energy
The notion of using solar cells placed under the skin to continuously recharge implanted electronic medical devices is a viable one. Swiss researchers have done the math, and found that a 3.6 square centimeter solar cell is all that is needed to generate enough power during winter and summer to power a typical pacemaker. The study is the first to provide real-life data about the potential of usi ... more
